Directions

Make the sauce: Whisk together hoisin sauce, soy sauce, rice wine vinegar, Sriracha, and sesame oil in a small bowl

Heat olive oil in a large skillet over medium-high heat. Add onions and sauté until soft. Stir in garlic and ginger and cook until fragrant, about 30 seconds. Add ground chicken and cook until browned and mostly cooked through, breaking up the meat with the back of a wooden spoon.

Pour in the sauce and cook 1 to 2 minutes more, until the sauce reduces slightly and the chicken is cooked through completely. Turn off heat and stir in chestnuts and green onions. Season with salt and pepper, to taste.

Spoon a large scoop (about 1/4 cup) of chicken mixture into the center of each lettuce leaf. Serve immediately.
